feat: introduce MEMBER_DELEGATE_DESCRIPTION for action mode protocols

- Added MEMBER_DELEGATE_DESCRIPTION constant to centralize the delegate instructions for action mode protocols, improving code maintainability.
- Updated buildActionModeProtocolText to utilize the new constant, enhancing clarity and reducing duplication.
- Enhanced messageStore and TeamProvisioningService to support filePath handling in attachments, improving metadata management.
- Updated type definitions to reflect the addition of MEMBER_DELEGATE_DESCRIPTION in the protocols interface.
